The library, therefore, should not enter upon these duties blindly or ignorantly. It is a great task which is thus undertaken--to educate the community to use books and to guide it in that use. Although small beginnings are possible, the work will inevitably grow on our hands just as that of the schools and colleges has done, and for similar reasons. But whatever difficulties lie in the way of their performance, it is plain that the library must assume these new duties. With many experiments, with many failures, with many partial successes, the library will extend its teachings, its conscious influences, until they touch the life of the community at every point. In this rambling talk I have discussed library work as it looks forward to new problems, and have devoted only a word, and that perhaps a rather disparaging one, to the traditional use of the library. I would not leave the subject in this way. For the traditional use of books remains and will remain the center of library work and the main source of its best influences. The problem of the library to-day, looked at from within and not from without, and in relation to other agencies, is essentially that which confronts the university. Both institutions once stood for culture and for culture exclusively. Both are now challenged by the spirit of the newer time and are called upon to justify themselves as public utilities. This they must do, and that in full measure, but there is a real danger that both, in the multiplicity of the new duties thus forced upon them, may forget the weighty words, "these ought ye to do and not leave the other undone." For, after all, the highest public utility which the library offers, or can offer, is the opportunity to cultivate the friendship of books. This utility is none the less precious because it is intangible. Indeed, it is the unique privilege of the library among municipal enterprises that it can provide a service which aids the higher life of the citizen so directly and so purely. In the spirituality of this function, the library stands second only to the highest institutions of pure learning, and to the church. No new undertaking, no extension of work, no plea of necessity can warrant or justify any loss of power on this highest level. The problem is not to discover how to sacrifice as little as possible of the old spirit to the new duties, but to learn how through the new duties we may make more wide-spread and more potent for good that oldest and best inheritance from the past--the love of books.
